Zenmap, GUI version of NMAP

NMAP is a tools used to gathering information on your target. NMAP can give you a lot of your target such as open port, target OS, target database, etc. NMAP is a very powerful tools because it has so many modes that can be used for scan the target which will give you ability too fool firewall, etc.

Zenmap is an NMAP with Graphical User Interface(GUI) support for easier use. To execute Zenmap in Kali Linux it is very simple. It is recommended to run Zenmap by using root privileges or some NMAP scan will not be available.

This will pop-up if you're not running Zenmap using root privileges :

And this is the fully running Zenmap will look like :

Notice in this Picture, I used my windows XP Virtual Machine(172.16.1.128) as the target. And we can select a scan profile. This scan profile will provide us with NMAP scan command. Here are some of the Scan Profile :

Intense Scan

-T4 : Scan Timing Mode 4 (See Description Below)

-A : Enable OS detection, Version Detection, Script Scanning, and traceroute

-v : Verbose mode, it will give detailed info of what the mmap is currently doing

Intense Scan with all TCP port scanned

-p 1-65535 : Scan the port range from port 1 to 65535

-T4 : Scan Timing Mode 4 (See Description Below)

-A : Enable OS detection, Version Detection, Script Scanning, and traceroute

-v : Verbose mode, it will give detailed info of what the mmap is currently doing

Quick scan

-T4 : Scan Timing Mode 4 (See Description Below)

-F : Fast Mode, will scan fewer port than the regular scan

If you notice, all of the scan above use -T4 which is Timing Mode 4. You can use from -T0 to -T5 (but only one at a time), and here are the description:

-T0 : Paranoid Scan

-T1 : Sneaky Scan,

-T2 : Polite Scan

This Scan will slow down the scan to use less bandwidth and target machine resources. This modes is used in IDS evasion.

-T3 : Normal Scan

This is the default scan used by NMAP if the timing mode is not declared in the command.

-T4 : Aggressive Scan

This Scan will speed up the scan with assumption that you are in a reliable network

-T5 : Insane Scan

This mode will scan with assumption that you are on a extremely fast network and willing to sacrifice accuracy for speed
